Players can participate in the Argent Tournament, a permanent event in northeastern Icecrown, to earn Champion's Seals. A representative of each race sells a race-specific pet. Horde characters may purchase this and other horde-based Argent Tournament pets once they have successfully "championed" that race's cause through various quests. Alliance characters may purchase this pet through a neutral auction house and on occasion through their own auction house.

I love this pet. I was relieved when they added it because I wasn't playing when the Vampiric Batling was around, and I was afraid that I'd never get my favorite animal in pet form. I like that it's brown instead of black and red, because that's more like the bats that live around here :)
